What is The number of protons in a chloride ion Cl- is?

A chloride ion (Cl⁻) has the same number of protons as a neutral chlorine atom, which is 17. This is because the number of protons, which defines the element, does not change when the atom gains or loses electrons to form an ion. Therefore, a chloride ion has 17 protons.


How many protons and electrons are there in a chloride ion?

Chlorine has 17 protons and an atom of Chlorine would have 17 electrons. However a Chloride Ion will have one more electron ie 18 electrons and will be negatively charged.


What is in a NaCl atom?

A NaCl (sodium chloride) atom contains one sodium (Na) atom and one chlorine (Cl) atom. Sodium has 11 protons and chlorine has 17 protons. They bond together through an ionic bond to form the compound sodium chloride.


How many protons and electrons does a chloride ion have?

Protons = 17, electrons = 18There are two isotopes differing in neutron number only :Cl-35 (75%) having 35-17= 18 neutronsCl-37 (25%) having 37-17= 20 neutrons
